Hello all-
I've been combing town for some TSP (Trisodium Phosphate) to clean
pepper seeds of little nasties.  The local Industrial Janitorial Supply
house has it---IN 50 POUND BAGS!!!!
Everyone else has the more friendly replacement- Sodium MetaSilicate
(NEW!!! TSP without the P!!!)  Does anyone know whether or not SMS can
be used for seed sterilization (of pathogens), and if so, at what
concentration and exposure time?? A pound of crystalline TSP would keep
me in seeds for years, as I would like to sterilize all my seeds at once
using Bosland's format of 10% TSP followed by 10% solution of regular
store bleach.  The old hardware store that previously handled it now
sells only SMS.
Thanks,
